Gas treatment

Gas treatment is the process of removing contaminants from gas streams, which can involve various methods and technologies. Its goal is to reduce the presence of harmful substances, such as toxic gases, dust, smoke, oil vapors and other pollutants, to ensure safety and protection of environment.

METHODS

• Mechanical filtration: This method uses filters and other devices to remove solid particles such as dust and smoke from the gas stream. Filters can be in the form of fabric bags, electrostatic filters etc.
• Absorption: This method is based on the chemical interaction of impurities with an absorbing liquid, resulting their extraction from the gas stream. The absorbed gases are subsequently regenerated during the extraction process.
• Adsorption: This method also relies on chemical treatment, but unlike absorption, gases are adsorbed onto the surface of a solid material which is called an adsorbent. Activated carbon or molecular sieves are often used in this process.
• Oxidation: In this method, pollutants in the gas stream are oxidized by catalysts or direct exposure to chemicals such as hydrogen peroxide or ozone.
• Reverse osmosis: This method is applied to treat gases containing oil vapors or other organic substances. The process is based on passing the gas stream through a semipermeable membrane principle that retains the contaminants, allowing only clean gas to pass through.
